WebUtility.HtmlDecode Method (String, TextWriter)
Converts a string that has been HTML-encoded into a decoded string, and sends the decoded string to a TextWriter output stream.
Assembly: System (in System.dll)
The output parameter cannot be Nothing if the value parameter is not Nothing.
If characters such as blanks and punctuation are passed in an HTTP stream, they might be misinterpreted at the receiving end. HTML encoding converts characters that are not allowed in HTML into character-entity equivalents; HTML decoding reverses the encoding. For example, when embedded in a block of text, the characters < and > are encoded as < and > for HTTP transmission.
